Known bugs/issues

Q: Why do I get lots of "Worker submitted share with hash > target:" in my P2Pool logs? It seems to put a large CPU load on P2Pool.
A: If you use cgminer, scrypt and stratum, this is because cgminer and p2pool disagree on how to represent difficulty targets on stratum. p2pool seems to use a sane definition of target difficulty, unfortunately most other pools didn't establishing a de-facto standard that cgminer follows. Current solution: use the "--fix-protocol" parameter of cgminer. It will force it to use getwork (instead of stratum) where both agree on how to communicate difficulty targets.
